Stepper motors are brushless synchronous electric motors powered by direct current that rotate in steps, keeping the rotor stationary under a specific power supply. A well-defined sequence of PWM ...

Here's a simple algorithm that uses conventional microcontroller blocks to control commercially available H-bridges to properly commutate a bipolar stepper motor through a microstepping profile.

Stepper motors exhibit a special feature: the ability to rotate the rotor shaft by a few degrees very precisely and without the need for sensors to detect the shaft’s angular position. In short, a ...

Find a downloadable version of this story in pdf format at the end of the story. A new controller IC, the L6470 for stepper motors, integrates the power stage along with a digital control core on a ...

Motion Control Products Ltd is launching the DMD556 next-generation digital microstepping drive that is claimed to benefit from unprecedented audio noise reduction (by 70%) and smooth low-speed ...

Many step motor users are faced with a question of whether or not to use microstepping in their stepper motor application. “What will it affect and how will I benefit from it?� one may ask.

Know the four most common microstepping myths. Myth 1: A high microstep count will result in evenly spaced steps at that count. Microstepping is good for smooth motion. However, having a 256 microstep ...

Stepper motors are now being used more frequently in industrial environments. Increased performance and reduced size make them increasingly attractive, and their application is no longer limited to ...

It’s increasingly common for designers to pair stepper motors with motion-control SoCs. In fact, more design engineers than ever are setting up SoCs themselves for motion applications. These chips ...
